Frequently Asked Questions
How does the ProGrid 72 (DE7220) compare to the ProGrid 60 (DE6020)?
Both are Hayward ProGrid vertical grid D.E. filters with identical features and 2-year warranties. The DE7220 has 20% more grid area (72 vs. 60 sq ft) — the longest cleaning intervals and highest capacity in the ProGrid residential line. It also ships taller (53.8 in vs. 47.8 in) and is slightly heavier (93 lb vs. 83 lb). Choose the DE7220 for the absolute maximum ProGrid capacity.
How much D.E. powder does this filter require?
The ProGrid DE7220 (72 sq ft) typically requires approximately 10–11 lb of D.E. powder after backwashing or reassembly. Always follow the specific amount in the owner's manual and use pool-grade diatomaceous earth.
Does this filter require backwashing?
Yes. D.E. filters are backwashed when pressure rises 8–10 PSI above the starting pressure. After backwashing, fresh D.E. powder must be added through the skimmer. Annual grid teardown and thorough cleaning is also recommended.
